.CAN-CAP-SOLDERING MACHINE..

SPECIFICATION forming part. of Letters Patent No. 365,316, dated June21, 1887.

Application filed March 9, 1887.

.To all whom it may concern:

Be it known that I, EDWIN NORTON, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement 4in Can-Cap-Soldering Machines, ofwhichthe following is a specification. My invention relates to machinesfor soldering caps on filled cans, and more particularly to improvementsupon can-capsoldering inachines of the kind heretofore patented to JohnG. Hodgson and myself in Letters Patent No.

v i340,148, of April 20, 1886.

My present invention consists, in connection with revolving can holdersand their moving-carrier and an acid or fiux applying brush or device,of an air or other duid pressnredevice forjetting and supplying the acidin measured`and definite quantities to each can. v

It A.further consists in the combination of a revolving can-holder, anacid-supply tank or reservoir, and air-purnps communicating with theacid-tank.

It further consists in providing such airpump with a valve or device forsuddenly releasing the fluid-pressure, and thus instantly stopping theflow of acid from the dischargenozzle.

It further consists, in connection with a revolving can-holder, of amovable molten solder-vessel provided with a valve for discharging themolten solder upon the can or seam to be soldered, anda valve-operatingpin adapted to engage or strike against the can as the soldering vesselor tool descends, and thus cause the can itself to open thesolder-discharge valve, so that if no can happens to be in place in thecan-holder the solder-.vessel may descend and the machine go through'its operations without discharging any solder.

It further consists in the novel devices and Serial No. 230,254. (Nomodel.)

ytional or diagram-view illustrating the operation of the acid-supplydevice. Fig. 4 is an enlarged detail elevation of the soldering device;Fig. 5 is an enlarged verticallongitudinal section of thesoldering-vessel. Fig. 6 is a detail elevation ofthe solder-dischargevalve, and Fig. 7 is ay detail elevation of the acidbrush and itsoperating device. Fig. 8 is a bottom view of the solder-vessel.

In the drawings, A represents the frame of the machine; B, the movablecarrier, upon which the revolving can holders or disks B B2 are mountedin the holder-frames B3 B3..

B4 B4 are the tracks upon which the carrier travels; B5, the chain ormechanism by which lthe can-holders are revolved; B, the heaters orgas-jets arrangedin the path of the canholders and at intervals equal tothe intervals between the canf-holders on the can-carrier. BT is thecooling device for cooling the cans after they are soldered, consisting,preferably', ofair-jet pipes arranged in the path of the can-holderslike the heaters.

B8 B9 are the gas and air supply pipes; Bm, a wire-solder reel; B, thewiresolder-feed ,whe-el, and B12 the Wire solder-guide tube.

B13 is'the cross-head or reciprocating slide, through which intermittentmotion is communicated to the chain-carrier B.

All these parts are fully shown and described in the prior patent beforementioned, and I here show and describe my invention as applied to acan-capping machine of this par ticular construction for sake ofconvenience.

My invention does not relate to the particular construction or operationof these parts,` and they therefore need not be here shown or describedin detail.

For more full description of `these parts of the machine reference ismade to the prior patent before mentioned.

My invention is applicable to other suitable forms of can-carriers,revolving can-holders, heaters, &c.

C represents the acid brush or device by which the acid or fiuxingmaterial is distribuyted over the joint. The brush C is mounted upon theend of a lever, c, which is pivoted to a bracket, c', secured to theupper track', B4. This lever carries an adjustable weight, c2, on itsouter end,by means of which the acid-brush IOO is elevated out of theway of the moving` cans, so that the head of the can will not besmearedwith acid as it advances into position. As eaclrean moves into position,the round head b ofthe stem b' of the upper can-holder disk, B',comes incontact with the rounded end c of the adjustable projection c on thelever c, and thus depresses the acid-brush until it comes in contactwith the joint. This meelr anism is also the same as that shown anddescribed in the prior patent before referred to, and for such mechanismany suitable equivalent or substitute device may be used in myinvention.

D represents the acid-tank,prelerably located on the frame of themachine below the `can carrier B.

D is the aciddischarge nozzle, connected by a pipe, D2, with theacid-tank. The acidtank D is a closed tank or reservoir1 so thatv theacid may be forced out through the nozzle D by compressed air Vforcedinto the tank near the top thereof.

D is an acidsnpply reservoir above the tank D and connected thereto by apipe, D, furnished with a stopcock, Di.

E represents an airpipe connecting the acidtank D with the air-pump F.The pipe E leads into thelend of the pump-cylinder F, and is furnishedwith an adjustable outlet or escape valve, d, so that by regulating thesize ot' this outlet a greater or less proportion of the air compressedby the pump may be forced into the acid-tank.' The piston F of the pumpor its stem F is pivotally con nected to an arm or projection, F3, onthe reciprocating cross head or slide B,which intermittently drives thecan-carrier B, so that the pump will be intermittently operated once foreach can as it is presented to the acid-brush C by the carrier B. Thepiston F of the pump is furnished with a valve-opening, f, and acheck-valve, f which is automatically closed as the piston F makes itsforward stroke to compress the air, and which valve is opened, so astoinstantl y release theair-pressure when the piston begins to make itsbackward stroke by means of a spring pin or catch, f2, which projectsthrough the pump-cylinder F near the rear end of the same and catchesona projecting lip or edge, f3,ot` the valve f. This yielding catch-pinis mounted in a suitable barrel or socket, f, and a coil-spring, f 5,therein forces the pin up to engage the pro jectionf as soon as thevalve passes the pin. The valve-opening f in the piston-head F is oflarge diamcter,so that the instant the valve f is open the air-pressureon the acid in the tank D will be instantly relieved and the dischargeof acid through the nozzle D instantly stopped. The piston-stem FL ismade hollow and provided with air inlet and outlet openingsf, and thereare similar air-outlet openings, f 7,through the end of thepumpcylinder.

The acid-discharge pipe D2 is provided with a stop or check valve, d',to prevent the acid in the pipe D2 iiowing back into the tank D,

and thus seeking its level after the air-pressure is relieved bytheopening of the valve f. This cheek-valve d keeps the acid-pipe D2 full,so that the acid will begin to discharge from the nozzle D the instantsufficient pressure is applied upon the acid in the tank D.

By means of the airoutlet valve l in the airpipe E the air-pressureproduced by the stroke ofthe pump on the acid in the tank D may beregulated or adjusted to any desired amount, and by this ineans,and bymeans of the cock d in the discharge-nozzle D', the amount ot' acidjetted upon the acid brush or can by each stroke of the pump-piston maybe regulated as desired. The reliefyalvef in the pumppiston serves toinstantly stop the flow of acid from the nozzle D the moment thepump-piston completes its forward stroke and begins to recede. Thedischarge-nozzle D' is or should be arranged, as indicated in thedrawings, to jet the acid upon the acid-brush C, and not directly uponthe can or its joint. The pumppiston F is operated to make its forwardor air-compressing stroke while the cross head or slide Bl" is makingits backward stroke-that is, while the caircarrier B is stationary. Theacid is thus jetted upon the acid-brush while the can-carrier isstationary and the can being revolved in its holder under theacid-brush.

XVhen the crosshead Bl makes its forward stroke to move the can-carrierB forward, the piston F makes its backward stroke and opens the valvef,thus relieving the pressure and cutting off the discharge et' acid fromthe nozzle D'.

G G represent the stirrer-bars for distributing the solder over theseam. The stirrerbars G are secured in an adj ustable socket, g, by aset-screw y', the socketg being adjustably ixed by a set-screw, g2, onthe arm y. The arm fj is pivoted by a pin, g," to a plate or projection,g, on the rock-shaft g". The shalt g" is furnished with a curved arm orshoe, G', having a notch or depression, gl. (See Fig. 4.) This shoe G'rides upon the can-holder frames B, and operates to automatically raiseand lower the stirrer-bars as the can-carrier moves intermittentlyforward. The construction and operation ol' these stirrer-bars are fullyshown and described in Letters Patent No. 356,469, dated January 25,1887, and are not of my invention.

H represents a vessel for containing molten solder. It is automaticallymovable up and down, and the lower end of this vessel serves as asoldering-iron to distribute the solder over the seam. Thismoltcirsoldcr vessel is moved up and down to bring the same into contactwith the seam to be soldered when the can is presented under the same bythe carrier.

The solder-vessel may be moved up and down by any suitable means ormechanism. It may, for example, be automatically operated by the sa'memechanism as that employed to operate the stirrer-bars G; and I haveusually connected the solder-vessel H with the adjustable socket-piece gby means of an arm,

4opening orLseat, h', and valve h2.

l h, fixed in the socket-piece by the set-screw g',

the samev as the stirrer-bars G are fixed. By-

moved into place under the same by the car! rier. If preferred, however,the solder-vessel H may be moved up and down by any other suitablemeans.

Thesolder-vessel His furnished with a valve The valve h2 is furnishedwitha hollow projecting'stem or pin, h3, having an opening or passage,h, for the admission -of the solder from the vessel H into the interiorof the hollow stem.

rlhe opening 7L through the wall of the hollow stem h3 may be adjustedinsize byV means of an adjustable rod or screw, h5, which projects upthrough the hollow sleeve or rod h6 of the valve. The adjustingscrew-rod h5 tits in a hollow threaded nut, hi, secured by screwthreadsin the end ofthe sleeve h. The adjusting-rod h5 is further provided withalstop- -nut, hito hold it in place. The hollow stem Y h of the valveprojects through the bottom or hase H of the solder-vessel, and when thesolder-vessel is depressed againstthe can it comes in contact with thecap orhead of the can, Iand is thus lifted sufficiently to open thevalve and permit the molten solder to fiow out upon the Y, seam. l

By means of the adj listing-rod, which regulates the size of thedischargeopening in the hollow stem h3, the amount of solder dischargedmay be regulated as desired.

Instead of making the sliding pin It", which operates by its contactwith the can to raise the valve, integral with the valve or rigidlysecured thereto, it may be made separate from the valve and mounted on adifferent part of the vessel H or its operating-arm l1, and conneeted inany suitable way or by any suitable mechanism with the Valve or itssleeve h, so that by the raising of the pin the valve will be opened andthe molten solder discharged upon the seam. form or perfectedconstruction of my invention to connect the operating-pin h directly orintegrally with the valve and to make such pin hollow, so that thesolder may be discharged n a ne stream through the pinitself. It ispreferable, also, to employ a slid-k ing valve; but other forms ofvalves may be used. der-vessel is made curved, to correspond to thecurve of the can-cap groove, as indicated in the drawings. j

The solder-vessel is preferably made of a single piece or hollowcasting, and it is furnished with a cover, H2, secured in place byscrews, so as to close the vessel tight and thus prevent Vthe oxidationof the molten solder.

The solder may be delivered into the vessel in any suitable way. I deemit preferable, however, to employ wire-solder and feed the It is,how-ever, the more improvedy The base or lower end, H', of the sol samegradually into the solder-vessel through asuitable opening, H3, in thecover H2 by means of asnitable wire-solder-feed device; and one featureof my invention consists in the combination of the movable valvedsoldervessel with a wire-solder-feed device. The wire-solder feed whichI prefer to employ is that shown and described in the prior patentsbefore referred to, and which is here indicated in the drawings. rIhesolder-vessel H is ldepressed against the can head or cap by its owngravity and thaty of the solder therein. The valve is also depressedagainst the valve seat to close the valve-opening by the gravity of theva'lve and valvesleeve. To increase thc weight, I load the valve-sleevewith a metal ball or other suitable weight, N. The solder in the vesselH is Vmelted and kept in a molten condition by a suitable heater, B,preferably a gasj et o'perating to project the fiame against the Vironvessel H, and preferably near the lower end of the saine, as indicatedin the drawings. I

My invention is not limited to the use of` ycan-'holders mounted uponmovable carriers, nor to revolving can-holders having two rcvolvingdisks. The upper disk of the canholder, which presses against thecan-capand serves to hold it in place, may, for example, consist simplyota` nonrotatable pin which presses against the center of the can-cap,and

.thus permits theean to revolve while thesolderingvessel is depressedagainst the seam.

I also desire it to be distinctly understood that my invention is notlimited to any particular kind of aircompression device, and that othersuitable or equivalent lmeans may be used in place of an air-pnmp forcompressing the air, and thus forcing the acid in measured quantitiesout of the acid-tank through the discharge pipe or nozzle. The acid-tankD should not be completely filled with'acid or flux, but a space shouldbe left above the acid forcom pressed air, as indicated by the dottedline t in the drawings.

As an equivalent construction, the soldervessel H may be made stationaryandthe rc- Volving can-holder made movable up and down without affectingthe operation of the solderdischarge valve or its operating-pin.
